Q: 0603，0805，1206，3020，3528，5050，355 what is the current and voltage of these patch LED? Please give advice!: LED patch: 0603, 0805, 1206, 1210, 5050. The 0603: conversion to metric is 1005, that of the LED element length is 1.0mm, width is 0.5mm. The trade is abbreviated as 1005, and the English name is 0603. The 0805: conversion to metric is 2125, that of the LED element length is 2.0mm, width is referred to as the 2125 inch 1.25mm. industry, it is 0805. The 1206: conversion to metric is 3216, that of the LED element length is 3.2mm, width is 1.6mm. The trade is abbreviated as 3216, and the English name is 1206. The 1210: conversion to metric is 3528, that of the LED element length is 3.5mm, width is 2.8mm. The trade is abbreviated as 3528, and the English name is 1210. The 5050: This is a metric called, said that the LED element length is 5.0mm, width is 5.0mm. Industry abbreviation 5050

Q: Production of a number of substrates, the use of SMD LED lights, red lights and green lights are not bad, blue lights appear mass dark, do not know why? Is the LED blue light material easy to use dark?: The pressure drop of the blue light is greater than that of the red light and the green light. If the series connection is the same as that of the green light and red light, the current limiting resistor will tend to dim

Q: What is the difference between SMT LED packaging with silicone and epoxy resin transparent package? What is the market situation of these two types of packaging?: To package with epoxy SMD beads are used in a lot of outdoor display, because the epoxy adhesive with good adhesion to all better PPI support in outdoor use, our high quality and inexpensive epoxy epoxy call for samples

Q: Indoor full color LED display module and LED what is the difference between a full color?: (1): LED full color light emitting module display module is generally yellow green, pure green module price is more expensive; SMD full color LED display using pure green tube coreThe display module (2): LED full color pixel visual feeling is thick, low brightness, easy to have the mosaic phenomenon; patch LED full color consistent, high brightness;(3): maintenance module LED full color display is not easy to maintain, the whole module replacement cost is high; SMD full-color LED screen for easy maintenance, repair and replacement of single lamp;

Q: What, in what way do I shunt the LED?: In series, the voltage is 20 times the rated voltage, in parallel, the voltage is rated voltage, but in tandem, a LED is broken, it is not bright, so it is recommended not to use it.

Q: Patch LED light does not flash, why?: Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.

Q: How to detect LED SMD beads: The output voltage of the digital clock diode file is not high, generally below 2.5V, so the measurement of LED lamp does not work, the best way is to external electrical measurement. If there are a lot of beads to measure it, can take a constant current power measurement.

Q: What does patch LED light mean?: Look, what's your product?. Some products have volume requirements, straight line will be relatively large, patches of small affixed to the circuit board does not occupy space, if only the light source, it may be an ordinary light bulb, as LED power saving.

Q: Which is good for LED patch and LED bulb?: LED (light emitting diode) patch (package)LED patch (SMD) made by FPC circuit board, LED, high quality silica gel. The waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising - Entertainment decorative lighting lighting field.LED bulbA solid state semiconductor device that converts electric energy into visible light by means of LED (light-emitting diode), which converts electricity directly into light; LED = Large, Electronic, Display,;

Q: Patch LED market conditions: Chinese suppliers also offer mature, but less profitable two-color and trichromatic products, which are mostly used in backlighting, appliances, consumer products, consumer electronics and display. Despite low market demand, vendors continue to offer sideview SMD LED, including 335 (4008), 020 (3806) and 215 (2810)
